3.2.4 What Options Are Used With Each Utility?

There are many utilities and it is not always easy to remember
all of the options and parameters associated with each.
Sometimes we need to run several utilities using nearly the same
options. For example, you may want to run several utilities
logging into a particular server. Rather than retype the
connection information each time, you would like to save the
option value some way and reuse it.

Fortunately, the mysqluc utility does this
and more. It is named the MySQL Users' Console and provides type
completion for options, utility names, and even user-defined
variables for working with common option values. Not only that,
it also provides the ability to get help for any utility
supported.
